Members of CIA (Center for Isotope Analysis)

Postdoctoral Scholar:

Dr. Ziliang Jin received his Ph.D. at the China University of Geosciences, Beijing. His PhD thesis project was to study the genesis of Skarn-type iron deposits, which supply the highest grade iron ores in China. He also worked as a guest scientist in the GeoForschung Zentrum (GFZ) SIMS lab in Potsdam, Germany. Since matrix-matched reference materials are critical for SIMS experiments, he worked on the Cameca IMS 1280HR instrument to develop and characterize reference materials, such as the synthetic glass, synthetic olivine, apatite and calcite. His current research work at ASU focuses on the study of water and hydrogen isotopic compositions in anhydrous minerals from the asteroid Itokawa and ordinary chondrites using the NanoSIMS 50L.

Graduate Students:

Jasmine Garani – She is a first year graduate student in SESE from Sharon, Massachusetts. She received her bachelor’s degree in physics and astronomy from Stony Brook University. She worked with Dr. Bruce Macintosh at Stanford University to analyze direct imaging data from the Keck Telescope and NIRC2 instrument in Hawaii in order to identify brown dwarfs that might harbor exoplanets. Her graduate studies will include isotopic studies of stardust and volatiles in meteorites. She practices a style of karate called ‘Uechi Ryu’ and is currently a 3rd degree black belter. She does rock climbing, and is looking forward to opportunities to explore parks in Arizona.

Zebdiah Teichert – He is currently a second year graduate student in SESE, and is being co-advised by me and Dr. Lynda Williams, an expert in terrestrial clays.  His interest is in using Li and B to trace the aqueous alteration and thermal history of organic matter in carbonaceous chondrite meteorites and terrestrial shales.

Jonathan Zaloumis – His doctoral research is to determine biogenicity of microdigitate stromatolites, and to understand the potential for sulfate-rich veins as a biosignature in terrestrial rocks as analogs to Martial rocks, using the NanoSIMS.

Kara Brugman – She is a 5th year PhD candidate in SESE and studies why volcanoes erupt by investigating diffusion chronometry in clinopyroxenes. Her interest in the field of diffusion chronometry allowed us to work together in developing new protocols for measuring volcanic rocks using the NanoSIMS.

Hannah Shamloo – She is a PhD candidate in SESE and also does diffusion chronometry of volcanic rocks using the NanoSIMS.

Melissa Sedler – A PhD candidate in astrobiology and environmental biogeochemistry in SESE, she is trying to decipher the nitrogen cycle in extremophiles from the Yellowstone National Park, using single-cell measurements with the NanoSIMS.

Undergraduate Students:

Jack Schulte – He is a sophomore studying Physics and Astrophysics. He is also a NASA Space Grant recipient (2018-2019). His main interests include stellar and planetary astrophysics, especially the study of presolar grains in meteorites. He is a private pilot and works part-time as an aircraft manager at Scottsdale Airport. He also owns a small reflecting telescope and spends an occasional night observing and photographing the Moon and neighboring planets.

Thomas Redford – He is freshman with a major in Math. His interests lie in understanding the formation of organic materials in stellar environments and in meteorites.

Ethan Duncan – He is a sophomore majoring in Astrophysics and minoring in Physics. He is a member of Barrett, the Honors College. He is interested in stellar and planetary Astrophysics especially in the formation of exospheres by particle bombardment on planetary surfaces. He has recently been trying his hand at astrophotography with a small refracting telescope on the weekends. He also performs part-time at Jesterz Improv Comedy Club at Mesa Riverview.

Victoria Froh – She is a sophomore double majoring in Chemistry and Earth and Space Exploration. She is in the Honors College and am a Gammage Scholar through Barrett. She is interested in the chemical origins/evolution of the universe. She is a captain of ASU’s Women’s Rugby team who competes D1 and finished top 16 in the nation in 2018. She is designing a new website for my research group.

High School Student:

Rithvik Musuku is a high-school student from BASIS Chandler. He works in the summers to research optimal ways of handling and mounting tiny (10-100 micron) particles.
